LAWN SPRINKLER.

Application mea November- 13, 1926. serial No. 148,180.

This invention relates to lawn sprinklers and has for one of its objects the provision of a sprinkler, which may be easily moved from one location to anotherwithout danger of tipping, and without requiring the water to be shut ofi'.

A further object of my invention is the provision of a sprinkler of comparatively low height, which is so arranged that the weight of the hose will not deflect the nozzle out of the normal position during or subsequent to the shifting movement. In this connection my invention is directed towards the construction of a sprinkler which may be cheaply manufactured and which is durable in use.

In the drawings Fig. 1 is a plan view of a sprinkler embodying my invention; Fig. 2 is a vertical section through thelongitudinal center of the sprinkler; and Fig. 3 is a section through the sprinkler taken on a plane indicated by the line 3-3 in Fig. 2.

The invention as illustrated comprises a body portion having` a pair of spaced runners 10 which are connected along part of the upper edge by a web 11. vThe runners have substantially uniform depth for the length of the web, but have an increased depth on one end beyond the web. Moreover, the runners are flared outwardly adjacent such end portions, as shown particularly in Figs. 1 and 3. A nozzle 15 may be swivelly mounted on the web adjacent the mid-portion of the rearward edge 12 and has provision for receiving a hose coupling indicated at 16. The swivel connection may embody a member 17 which is threaded onto the web, and which has a protruding portion 18 extending above the web and having an annular groove 19 therein. A block 20 surrounds the protruding portion and in turn is mounted between downwardly projecting arms 21 which preferably form part of the body of the nozzle. A pin 25 extends through the arms and the block, and also tangentially through the groove 19 for permitting the nozzle to be swiveled about the body, and at the same time for holding the cooperating parts together. In this way the body may be positioned on uneven ground without causing the stream to be deflected from a vertical position. The dotted lines 10a and 10b in Fig. 2 illustrate two possible positions of the body with reference to the nozzle.

The flared runners being higher than the distance of the web above the ground, pro- ,videy adequatestops for the hose, while the sprinkler is vbeing moved from one location to another, and by limiting the turning radius to prevent tipping of the device. The extreme positions of the hose are illustrated by the broken lines27 and 28 in Fig. 1 while the normal position is shown by the full lines 29.

To facilitate turning of the sprinkler I employ a bail 30 which may be suitably4 fastened to the runners, and may utilize a ring 31 whichslides around the bail and is arranged to be attached to a cord or chain 32. The bent portion of the bail near each end extends beyond the runners, as at 33, and facilitates turning of the sprinkler.

A swivel connection between the nozzle and body is illustrated as being on part of the web which is depressed with relation to the main portion of the web. This permits the swivel connection to be comparatively low, wherefore the stream may not be deflected from a vertical direction by the weight of the hose. Thus, I obtain a sprinkler which embodies principally a one-piece casting which maybe cheaply manufactured and yet provides a satisfactory nozzle support, which permits shifting of the nozzle 1n a convenient manner. y

Il claim:

1. A lawn .sprinkler having a pair of flared runners and a connecting web terminating short of the end of the runners, a noz-` zle pivotally mounted on the web adjacent the mid-portion and along one edge thereof, said nozzle having a hose connection associated therewith leading away from the web, each of the runners being flared upwardly on opposite sides of the nozzle and adapted to engage the hosey to limit the degreesfof turning movement of the body with reference to the nozzle, and a bail associated with the body on the end opposite the flared part of the runners.

2. A lawn sprinkler comprising a body portion having a pair of runners and a connecting web, ,they runners being of a substantially uniform depth throughout the length of the web and being flared upwardly and outwardly beyond the web, a member attached to the web protruding beyond the top.- surface thereof and having an annular groove associated therewith, a nozzle surco f rounding the member, a connecting pin eX- tending through the nozzle and said groove for providing a pivotal connection between the nozzle und the body7 a hose Connected to 'the nozzle, said tiered portion ot' the runners beingadapted to engage the hose to limit the turning movement of the sled Withreference to the nozzle, and a bail associated with the runners.

3. A lawn sprinkler comprising a body portion having' runners und a .connecting men'lbeign nozzle and hose connection swivelly Connected to seid Connecting member, the runners bei ng flared outwardly und upwardly to the reur of said connecting member and in the path of lateral movement of the hose attached to said Connection to provide a stop for limiting the swinging movement of the hose with reference to the body.

4. `A lawn sprinkler comprising e. body portion having a pair of runners and a oonnecting .web7 a nozzle and hose connection swivelly mounted on the web, and u hail assooiate'd with the body portion, said bail having the end portions bent into the form of loops which extend laterally beyond the sides of the runners.

In testimony whereof, I hereunto affix my signature.v
